No they aren't, but they directly used audio from it.

There's a difference between WoW having a character named Harrison Jones who's largely a parody of Indiana Jones who's quests are archaeology based and kinda silly. It's another thing entirely if they used repurposed clips from Raiders of the Lost Ark for his voicelines.

There's more going on.

I’ve seen a number of references to my work in big-company projects before. For example, there’s a dead unicorn with an enchanted kidney named Charlie in World of Warcraft. This is fine! It’s completely within fair-use laws. Using my audio directly is not fair use.

Copyright law, at least in the United States, is heavily weighted towards protecting large corporations. Warner Bros is one of the largest media companies in the world, and it often uses IP law like a weapon against smaller artists. Notable examples include MeatCanyon, whose clear fair use parody video “Wabbit Season” was forcibly removed from YouTube, and Vera Drew, whose parody film “The People's Joker” received a cease and desist letter from WB, initially derailing its film festival premiere schedule.

So WB wasn't just making a reference, but also lifting audio from Steele's work while also shutting down other's fair use parodies.

Plagiarism is theft, idiot.
